[Osteoma cutis. Multiple miliary osteoma of the face].

Primary and secondary forms of ossification can be distinguished on the basis of the skin, with osteoma cutis occurring in primary forms. Three entities can be differentiated: solitary and generalized osteoma cutis and multiple miliary osteoma of the face. Clinically, multiple papules 2-3 mm in diameter are present, which histologically consist of bony trabeculae enclosing mature fat cells and, occasionally, marrow cells. We describe the clinical, radiological and histological features of a case of multiple miliary osteoma of the face in an otherwise healthy 55-year-old woman.
